Reaction force

[gregorsky]

Hi,
In our model we use only hexa elements with simple boundary conditions and applied force. Step is Linear Perturbation. As a result we receive very strange results in reaction force:

RF.Magnitude RF.RF1 RF.RF2 RF.RF3
@Loc 1 @Loc 1 @Loc 1 @Loc 1
---------------------------------------------------------------------------------
Total 119.941E+03 -100.0000E+03 927.073E-09 143.051E-06


Where this value of Maginitude comes from? Any idea?

Regards,
Greg

Hi,
What is this loc 1,
I assume that it is one of the nodes which is constraint
Anyhow resultant is always root mean square value
Does this happens for sum of all constraint nodes
I mean let us sum RF1 for all nodes..similarly RF2 RF3 and RF.magnitude
That sum of RF Magnitude should be root (sum of square of 1 2 3)
